Abstract:At neonatology departments, several body parameters of newborns are checked daily with multiple devices. These devices rely on batteries, requiring frequent recharging or replacement. The battery lids or charging connectors make these devices difficult to sterilize. This project presents a wristband device that addresses the problems with current portable medical equipment. Instead of a battery, a supercapacitor was used, which is more durable and can be charged in less than 5 seconds. Furthermore, wireless charging technology was implemented, allowing for a sealed and thus sterilizable device. The developed prototype includes optical sensors for measuring bilirubin levels, blood oxygen levels and body temperature. Measurements are performed by briefly pressing the device against a patient’s skin.
